CARCASS-CUTTNG DEVICE.

Application mea april 23, taf/:a serial ivo. ceases.

f Tio all whom t may concern:

Be it known that I, DANIEL I. RENDLGH, a citizen ot the United States, residing at South St. Paul, in the county of Dakota and( State of Minnesota, have invented certain specilication.

.Ny invention relates to devicesused in' slaughter houses for opening' the vbodies of hogs, calves and othersmall animals preparatory to removing the insides therefrom4 tand the object is to provide an improved,{ efficient device of said kind.

In the accompanying drawing:

l Figl is a top view of the improved dey vice.

Fig. 2 is a side view of Fig; 1, with the mechanism shown in two positions one 0I Vwhich is in dotted lines.

Fig. 3 is a section on line 3-3 in Fig. 2 with the cutting blade omitted. f

4 is a section on line 4 4 in Fig. 2 but modified.

Fig: 5 is a; right hand end view of Fig. Il.

Fig. Gis a section on line 6-6 in Fig. 2.

7 is a section on line 7m7 in Fig. 2 with the link 26 detached From the operating lever and l'folded over to the right` and `the attaching' `03F-the cutter blade to the framel modified. Fig'. 8 is a top view of lever arm 28;V

Referring to the drawing` by reference numerals. the space between the lines 1() in Fig. 2V indicates the thickest part of the front of the carcass to be cut open, and the device shown in operation in said view is drawn on a scale corresponding' to such thickness.`

(The actual thickness at thebreastbone ot hogs and small cattle is not supposed to eX- ceed two and one-halle inches. and hence my 'dra-wing' is practically rone-half ofi-full size.)r

11 is a main body piece of the device curved at 12 to form a leg,r 13 and has its upper end termed with an eye-sh aped handle or hand hold 14..- and adjacent thereto a small arm 15. Suitably secured to the leg 13 at about right angles there is a long finger 16- a. point 23. The blade is near its back prod` vided with a hole 24:., preferably in a lug 25 "-which serves to bring' theend of aV 26 above the blade toll'eave the latter freeto cut fullyV into the flesh. Said link 26 has its upper end pivcte'd at 2.7` to the short arm 28 of a hand lever 28-29 which is fulcrum'ed at 30 to the arml, T he arm 28 may have a slit 28a 'for theblade. I

In Fig.' 2 is show-n at 29a that thehand lever'29 may be offset so as yto -more fully clear the ysurface of' the carcassV 10, operated on. i

Pivotedat 29a-is a rack29b adaptedto en-A' gage a tooth 299011 the handle 14;. 29dis a springv holding-the *rack*` normally disengagged.

TheA l3is preferably secured tothe fin-v" provide'for in several' ways; thus in Figs. 1, Y

v 2 and3 'l' have shown a pivot 31 and a screw 32. By removing'said screw thelinger `may be swung; on the pivot out of the way for a Agrinding' device.

In Figs. and 5 only one screw 33 isrused andthe-finger 1.6.has its rear vendto'rinefl with inwardv notches 34 in which the les;l13 is heldV against swinging on thefscrew 33. lexceptgwhen the screw is partly unscrewed. whenthe notched parts l maybe sprung' apart and permit the vfinger to he swung out ot the way for 'grinding ot the blade.

In Fig. lpthe blade is shown. as being offset at 35 to brinnyit'into plane with theslit 17 in vthefinger and the blade is pivoted tothe side Y of the piece 12J-.13. But this is so modilied in @that the bladeA is fitted and pivoted Aobvious `that two parallel links or even one link will also serve the purpose. I therefore do not wish or mean to limit the invention to any of such minor variations.

In the operation of the device the carcass to he gutted 1s usually suspended by the hind legis from a carriage having wheels rolling,V

on a rail ,or rails. each'carcass having been nreviouslv cut or given a so-called Csticking hole in liront ot the collar bone.

To cut. the carcass open the operatoriotmy device inserts the linger 16 into said` sticking; hole as tar as it will go when v diafragrn of the` carcass.

blade 19 iss'pread away fromvthe linger.

fr ith one hand on handle 14 and the other on lever 29 the operator now pulls the device as fromv headto tail ofthe carcass While repeatedly swinging the lever 29 toward and away Vfrom handle 14. This. .of course, operates the blade 19 and vcuts the carcass open in a very short time asv compared with the use of devices heretofore used. Y

' The point 1,6a .of the linger is Vsharp enough to be readilyY forced through the vIn cutting open the belly portion no shearing movement may -be necessary, the operator merely holds the rack vengaged with Vthe tooth 29c so .as lto lzeep the blad@ lopen@ the desired degree .While be `pulls the .device along and rps'the tellyy open.
